ABB Bailey PHARPS32200000 F8-G2B9B3B6 MPS III Multi-Output Rack Power Supply Module

PHARPS32200000 with order code F8-G2B9B3B6 is ABB Bailey MPS III modular multi-channel power supply, dedicated to INFI 90 / Symphony Harmony DCS rack systems. It converts wide-range AC mains into five groups of isolated regulated DC power, providing stable power for controllers, analog/digital I/O boards, communication cards and field sensors inside the DCS cabinet, eliminating voltage fluctuation interference to guarantee uninterrupted process control operation.

This hot-swappable rack-mounted power unit adopts forced air cooling and full metal shielding housing, with built-in multi-layer hardware protection circuits. Original production has been discontinued, now it is a core aftermarket spare part for overhaul, replacement and backup of aging thermal power, petrochemical and papermaking Bailey INFI90 DCS control racks.

Core Functions

Supply multi-group isolated stabilized DC power to all boards inside INFI90 DCS rack, meeting different power requirements of CPU, signal acquisition and communication modules separately.
Full galvanic isolation between each output channel to suppress ground loop noise and electromagnetic interference from high-voltage field equipment, improving signal sampling accuracy.
Complete hardware fault protection logic: automatically cut off abnormal output and trigger cabinet alarm when overload, short-circuit or overheating occurs to avoid batch damage to DCS control boards.
Hot-swap support allows single power supply replacement without full DCS system shutdown, greatly shortening equipment maintenance downtime in continuous production factories.
Built-in load balance and voltage compensation circuit, maintaining stable DC output voltage even under frequent dynamic load changes of process control systems.
Standard Bailey rack unified mechanical and electrical definition, plug-and-play replacement without modifying cabinet wiring or adjusting system power parameters.
